The trail begins at the locked gate here, follows the fire road through French Ranch Open Space Preserve, and continues onward to Barnabe Mountain in Samuel P Taylor State Park. Excellent views all along the ridge.

Get off the highway and help promote safe bikeways in the San Geronimo Valley! School trail is mostly well-compacted gravel, a great alternative to parallel but out of sight and danger of busy Sir Francis Drake Boulevard. Currently only this short section between Forest Knolls and Lagunitas School. Great start people, extend the trail !

293 forested acres overlooking the heart of San Geronimo Valley. Primeval groves of bay and redwood trees are the star attractions here, where scenes in George Lucas' The Ewok Adventure were filmed. For a peaceful getaway, meander down Roy’s Redwoods Loop Trail. It's a secluded ridge with sheltering fir, madrone, and oak trees. Look for "hippie trees." A 60's commune made their homes inside large hollowed-out trunks. https://www.marincountyparks.org/parkspreserves/preserves/roys-redwoods
